the second one, i am not that big of fan of, its added for no real purpose to me.. you know? like i know there will not be ripples in a car hood.. the effect doesnt match with the image..

the first one has promise.. i like the blue, and the emphasis on form.. but i think it should be all blue.. so lose the turn signal, or convert it to something neutral.. and then you are going to have to do something about that noise in the bottom part, it ruins the form by taking away from the smooth blue color...

overall, i think you are on to something. just work out the details.. and consider a closer/lower perspective as well, i think you will capture the form of the hood better that way..
